Summary
An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by specifying the value of `userInfo`. When `userInfo` is passed into the `addWewifiWhiteUser` function and processed by `sscanf` without size validation, it could lead to a buffer overflow vulnerability.

CVE-2026-24110 (GCVE-0-2026-24110)

Vulnerability from nvd – Published: 2026-03-02 00:00 – Updated: 2026-03-02 16:07

Summary
An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may send overly long `addDhcpRules` data. When these rules enter the `addDhcpRule` function and are processed by `ret = sscanf(pRule, " %d\t%[^\t]\t%[^\n\r\t]", &dhcpsIndex, dhcpsIP, dhcpsMac);`, the lack of size validation for the rules could lead to buffer overflows in `dhcpsIndex`, `dhcpsIP`, and `dhcpsMac`.

CVE-2026-24113 (GCVE-0-2026-24113)

Vulnerability from nvd – Published: 2026-03-02 00:00 – Updated: 2026-03-05 15:54
VLAI?
Summary
An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by controlling the value of `nptr`. When this value is passed into the `getMibPrefix` function and concatenated using `sprintf` without proper size validation, it could lead to a buffer overflow vulnerability.
Severity ?
9.8 (Critical)

CVE-2026-24110 (GCVE-0-2026-24110)

Vulnerability from cvelistv5 – Published: 2026-03-02 00:00 – Updated: 2026-03-02 16:07
VLAI?
Summary
An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may send overly long `addDhcpRules` data. When these rules enter the `addDhcpRule` function and are processed by `ret = sscanf(pRule, " %d\t%[^\t]\t%[^\n\r\t]", &dhcpsIndex, dhcpsIP, dhcpsMac);`, the lack of size validation for the rules could lead to buffer overflows in `dhcpsIndex`, `dhcpsIP`, and `dhcpsMac`.

CVE-2026-24113 (GCVE-0-2026-24113)

Vulnerability from cvelistv5 – Published: 2026-03-02 00:00 – Updated: 2026-03-05 15:54
VLAI?
Summary
An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by controlling the value of `nptr`. When this value is passed into the `getMibPrefix` function and concatenated using `sprintf` without proper size validation, it could lead to a buffer overflow vulnerability.
